Description
Technical Field
The invention relates to the field of daily chemicals, in particular to a softener composition with a fabric quick-drying function and a preparation method thereof.
Background
Currently, fabrics are often dried by air drying or oven drying after being washed. The longer the drying time, the more the life convenience is affected, and the energy consumption may be increased. Therefore, it would be beneficial to shorten the fabric drying time. The fabric softener is usually added in the last rinsing procedure, so that the beneficial ingredients can be deposited on the fabric, and the fabric is endowed with unique functions, such as the effect of lasting fragrance retention by adding microcapsule essence.
Patent CN 103764811A proposes that the N- (-CH) is a compound of2-CH(OH)-CH2-Cl)2The drying time of the fabric can be reduced by washing the fabric at least 3 times with a composition of a linear polyether polymer having a terminal weight average molecular weight of less than 5000 to deposit the linear polyether polymer on the fabric. However, the composition needs to be effective after accumulation treatment, has low efficiency, and has poor biodegradability of beneficial components, which is not beneficial to environmental protection.
Many factors influence the drying speed of the fabric, such as the surface tension of the treatment liquid, the contact angle of the fabric base surface, the hydrophilicity and hydrophobicity of the fabric, and the like. Generally, the fabric is dewatered after being rinsed, water carried on the fabric is thrown off as much as possible, the lower the liquid carrying rate of the fabric is, the shorter the relative drying time is, and the energy consumption is saved. In conclusion, the development of a softener with a fabric quick-drying function has market demand.
Disclosure of Invention
In order to solve the technical problems, the invention provides a softener composition with a fabric quick-drying function and a preparation method thereof.
The specific technical scheme of the invention is as follows: a softener composition with a fabric quick-drying function comprises the following components in percentage by mass:
0.05 to 5 percent of microcrystalline cellulose,
3 to 15 percent of cationic surfactant,
1 to 10 percent of emulsifier,
0.3 to 5 percent of rheology modifier,
the balance of water.
And the pH value of the 1wt% deionized water solution of the softener composition is 3.0-6.0.
The softener composition contains microcrystalline cellulose with special specification, and after the fabric is treated by the softener composition, the liquid carrying rate of the dehydrated fabric can be obviously reduced, the drying time is shortened, and the quick-drying effect is realized. The general principle is as follows: in the rinsing process, the microcrystalline cellulose is deposited on the fabric, so that the hydrophobicity of the fabric is increased, the adsorption and combination capacity of the fabric to water is weakened, the liquid carrying rate of the fabric after dehydration is reduced, meanwhile, in the airing or drying link, the acting force of the fabric and the water is weak, the moisture is more easily volatilized, and the drying time is further shortened.
In addition, it is noted that the pH of a 1wt% deionized water solution of the softener composition of the present application needs to be in the range of 3.0 to 6.0 in order to prevent the esterquat from hydrolyzing under alkaline conditions, destroying its structure.
Preferably, the microcrystalline cellulose is cellulose I type, the average particle size is 10-100 μm, the crystallinity is 55-85%, and the degree of polymerization is 100-250.
Further, the microcrystalline cellulose has an average particle diameter of 30 to 80 μm, a crystallinity of 60 to 80%, and a degree of polymerization of 150-.
The inventor of the application finds that the microcrystalline cellulose with any specification can not obtain ideal effects, and experiments find that the size of the microcrystalline cellulose has great influence on the quick-drying effect, and the quick-drying effect is more obvious only when the microcrystalline cellulose is within the specific size range. Microcrystalline cellulose which is not within the specified specification range has little effect on quick drying, and may be dependent on factors such as deposition ability, film forming ability, and hydrophobic property.
Preferably, the mass percentage of the microcrystalline cellulose is 0.1-2%.
Tests show that the content of microcrystalline cellulose has a certain influence on the quick-drying effect, and if the addition amount is too low, the amount of microcrystalline cellulose deposited on the fabric is very small, so that the quick-drying effect is difficult to bring; and if the addition amount is too large, the requirement on the suspension stability of the system is high, and adverse effects are generated.
Preferably, the cationic surfactant comprises one or more of alkyl quaternary ammonium salt, ester quaternary ammonium salt and imidazoline type quaternary ammonium salt.
Further, the cationic surfactant is an esterquat surfactant, which may be Stepandex VT-90 from Stepan, Rewoquat WE45 from Evonik, and Prapegen TQN from Clariant.
Preferably, the emulsifier comprises one or more of fatty alcohol-polyoxyethylene ether, fatty acid-polyoxyethylene ether, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, alkyl glycoside, fatty acid ethanolamide, and sucrose fatty acid ester.
Preferably, the rheology modifier comprises one or more of a polyurethane polymer, a polyacrylamide polymer, and a polysaccharide polymer. Suitable rheology modifiers are water soluble or water dispersible, preferably cationic polymers. Further, the rheology modifier is a cationic polyacrylamide based polymer, which may be Flosoft 270LS from SNF and Rheovis FRC from Pasteur.
Preferably, the composition has a yield stress value at 25 ℃ of not less than 0.2 Pa.
Microcrystalline cellulose is a water insoluble particle, and therefore a certain yield stress of the system needs to be maintained to ensure that microcrystalline cellulose can be well suspended and stabilized in the system (controlled by controlling the content of the rheology modifier). If the yield stress value of the system is too small, the microcrystalline cellulose will settle out.
Preferably, the softener composition further comprises one or more of a pH adjuster, hydrophilic silicone oil, a whitening agent, a preservative, an inorganic salt, a fragrance, and a pigment.
A method of making a softener composition comprising the steps of:
a) mixing, dispersing and dissolving a cationic surfactant and an emulsifier in water, and uniformly stirring;
b) adding a rheology modifier into the solution, and uniformly stirring;
c) adding microcrystalline cellulose into the solution, stirring uniformly, adding other auxiliary agents, and finally adjusting the pH value.
Compared with the prior art, the invention has the following technical effects: the softener composition contains microcrystalline cellulose with a specific specification, can obviously reduce the liquid carrying rate of the dehydrated fabric, shortens the drying time, realizes the quick-drying effect, and has good stability.
Detailed Description
The present invention will be further described with reference to the following examples.

The yield stress and stability of the softener compositions and the quick drying effect are shown in Table 2, respectively.
TABLE 2 related Properties of softener compositions
As can be seen from table 2, the above softener composition has good high and low temperature stability under a certain yield stress of the system. But only the microcrystalline cellulose with a specific specification has an obvious quick drying effect, the liquid carrying rate of the treated fabric is low, and the drying time is shorter. If the particle size and crystallinity of the microcrystalline cellulose are not within the specific ranges (the particle size in example 5 is larger and the crystallinity in example 6 is lower), the quick-drying effect is relatively poor.
The components were weighed according to the formulation in table 3 and the softener composition was prepared as follows: firstly, mixing, dispersing and dissolving a cationic surfactant and an emulsifier in water, and uniformly stirring; adding the rheology modifier into the solution, and uniformly stirring; and adding microcrystalline cellulose into the solution, stirring uniformly, adding other auxiliary agents, and adjusting the pH value to 5.0 +/-0.5.

TABLE 4 associated Properties of the softener composition
It can be seen from the above table that when the yield stress of the composition system is too low (example 14), it is difficult to stabilize the microcrystalline cellulose by suspension, and delamination occurs. Meanwhile, along with the increase of the amount of microcrystalline cellulose in the system, the quick drying effect of the composition is better, but the effect improvement proportion is gradually not obvious.
The components were weighed according to the formulation of table 5, and the softener composition was prepared as follows: firstly, mixing, dispersing and dissolving a cationic surfactant and an emulsifier in water, and uniformly stirring; adding the rheology modifier into the solution, and uniformly stirring; and then adding microcrystalline cellulose into the solution, stirring uniformly, adding other auxiliary agents and adjusting the pH value to 4.0 +/-0.5.
TABLE 5 composition of softener compositions
TABLE 6 relative Properties of softener compositions
The hydrophilic silicone oil is added into the softener composition system to improve the hydrophilic performance of the treated fabric, but as can be seen from the table above, the addition has a certain influence on the quick-drying function of the composition, so that the amount of the hydrophilic silicone oil in the composition can be controlled. According to experimental results, the addition of microcrystalline cellulose with a specific specification into the softener composition can obviously reduce the liquid carrying rate of the fabric, shorten the drying time and have a quick-drying effect.
